EMPROVEMENT IN SETTINGS FOR HOT-AIR FURNACES.

Specification forming part of Letters Patent No. 128,179, dated June 18,1872.

To all whom it may concern:

Be it known that 1, CHARLES J. SHEPARD, of Brooklyn, Kings county, NewYork, have invented, made, and appliedto use improvements in setting forfurnaces and heating apparatus for dwellings and other buildings; andthat the following is a full, clear, and correct description of thesame, reference being had to the accompanying drawing making part ofthis specification, and to the letters of reference marked thereon,inwhich- Figure 1 is a vertical cut section of my improved setting. Fig. 2is a vertical out section of the same, the furnace or heater beingplaced in position.

In the drawing, like parts of the invention are pointed out by the sameletters of reference.

The nature of the present invention consists in an improvement, as morefully hereinafter set forth, in the construction of setting for furnacesor heaters intended to heat buildings; the object of the invention beingto so construct the setting that the largest amount of heat-retainingsurface shall result.

To enable those skilled in theart to make and use my invention, I willdescribe the same.

The setting in the present instance is composed of an outer casing, A,of brick, within which is placed or constructed an interior wall orcasing, B, surrounding the furnace or heater 0. The inner wall or casingsurrounding the furnace O I propose to make circular, and to constructit so that every alternate row of bricks, or each alternate brick, shallproject beyond the face of the Wall one-half of its length, making it,as it were, a spicula of brick throughout the entire surface. Within theinner wall of bricks, constructed as just described, the heater orfurnace is placed, the pipe from the same passing through the inner andouter casings, and access to the same being had by means of slidingplates secured in the front of the outer casin g.

In the present instance it will be seen that, by projecting the bricksas shown, five sides of each brick so caused to project are employed asa heat-retaining surface, and that by arranging the bricks in alternaterows, the air supplied to the furnace is allowed to circulate freelythrough the casing and become heated in such passage, and is thensupplied to the buildings through the pipes introduced into the top ofthe casing A.

Having now set forth my invention, what I claim as new is I Thecombination, with the outer casing A, of an inner casing or setting, B,constructed substantially as described, for the purpose specified. 7
